DESCRIPTION -
Surf actant for use in external preparations for skin and
external preparation for skin containing the same
TECHNICAL FILED
The present invention relates to a surfactant for
use in external preparations for skin and to an external
preparation for skin containing it. More particularly,
the present invention relates to a surf actant for use
in external preparations for skin having low skin
permeability (penetrability) and low irritation, an
external preparation for skin, such as cosmetic,
containing such a surfactant, and an external
preparation for skin, such as a transparent cosmetic,
containing such a surfactant and a sequestering agent.
BACKGROUND ART
Hitherto, in external preparations for skin, such
as cosmetics, there have been used anionic surfactants
composed of aliphatic higher alcohol sulfates,
aliphatic higher alcohol phosphates, N-long chain acyl
glutaminates, etc., ether type nonionic surfactants,
e.g., aliphatic higher alcohol ethylene oxide adducts,
nonionic surfactants composed of higher fatty acid and
polyhydric alcohols, as emulsifiers, dispersants,
solubilizers, etc.

However, skin irritation of these surfactants
cannot be said to be sufficiently low to individuals who
have allergic constitution, suffering, e.g.,
pollenosis, atopic dermatitis, etc. so that external
preparations for skin containing such have insufficient
safety to skin and improvement thereof has been desired.
Further, even if external preparations for skin are
prepared using surfactants having sufficiently low
irritation to the skin, the external preparations for
skin contain in addition to surfactants irritating
substances such as salicylic acid, paraben or
hexachlorophene as an antiseptic. Therefore, in order
to reduce their irritation to the skin, development of
low irritation external preparations for skin has been
desired.
Known examples of low irritation surfactants
include amino acid derivatives. For example, there have
been proposed basic amino acid derivatives produced by
reacting a glycidyl ether and a basic amino acid
(Japanese Patent Application Laid-open No. Hei 9-271655
(European Patent Application Laid-open
No.788,832(A1)), and certain water-soluble glycoxide
type surfactants as a surfactant having low irritation
and alleviating the irritation of other skin-irritating
substances (Japanese Patent Application Laid-open No.
Hei 9-235587).

CA 02333601 2000-11-28
Further, with view to prevent glycine derivatives
from coloring and deterioration, there have been
proposed detergent compositions having blended therein
a metal chelating agent and an antioxidant (Japanese
Patent Application Laid-open Nos. Hei 9-78085, Hei
9-87673, and Hei 10-237488). However, these surfactants
have problems that they are not fully satisfactory in
low irritation, they have low effect of reducing
irritation by irritating substances other than
surf actants, they decrease the surface activity of other
surfactants, their deterioration cannot be prevented
completely, and so on.
DISCLOSURE OF THE INVENTION
Therefore, an object of the present invention is
to provide a surf actant for use in external preparations
for skin, having low irritation to the skin.
Another object of the present invention is to
provide a surfactant for use in external preparations
for skin, not only having low skin irritation to the skin
itself but also reducing the irritation of skin-
irritating substances.
Further, an object of the present invention is to
provide an external preparation for skin, such as a
cosmetic, containing the above-described surf actant for
use in external preparations for skin.

Furthermore, an object of the present invention is
to provide an external preparation for skin containing
the above-described surfactant for use in external
preparations for skin, retaining transparency for
cosmetics required of transparency.
The present inventors have made intensive research
with view to achieving the above-described objects and
as a result they have found that when used as a
surfactant, a compound produced by fermentation by
prokaryotes such as Bacillus microbes is low in skin
penetrability, is low in irritation to the skin and,
surprisingly, has an effect of reducing the irritation
by skin-irritating substances.
Further, the present inventors have found that
existence of a minute amount of an alkaline earth metal
such as calcium or magnesium in external preparations
for skin containing the above-described surfactant
results in that the surfactant and the alkaline earth
metal form a water-insoluble salt, which precipitates
and make the preparation turbid whereas blending a
sequestering agent together with the surfactant in the
external preparation for skin prevents the formation of
the water-insoluble salt of the surfactant without
affecting the low irritation of the surfactant and the
effect of reducing the irritation of skin-irritating
4
CA 02333601 2000-11-28
substances, so that transparency of the preparation can
be retained.
Based on these findings, the present invention
provides a surfactant for use in external preparations
for skin, an external preparation for skin, and a
cosmetic as described below.

Typical examples of the lipopeptide compound
derived from a prokaryote includes surfactin. Surfactin
is a compound, which is produced usually by a prokaryote,
has a lipopeptide structure represented by the formula
1 below.
RCHCH2CO-L_GIu-L_Leu-p_Leu-L_Vai-LAsp-p_Leu-L_X
O
wherein X is leucine, isoleucine or valine, R has 9 to
13 carbon atoms and represents a n-alkyl group, an
isoalkyl group or an anteisoalkyl group.
Generally, Bacillus microbes are used as the
prokaryote. Specific examples thereof include Bacillus
subti.lis IAM 1213 strain, IAM 1069 strain, IAM 1259
strain, IAM 1260 strain, IFO 3035 strain, ATCC 21332
strain, etc.
Surfactin can be obtained without difficulty by
cultivating these microbes and purifying lipopeptide
compounds that the microbes produced. Purification can
be performed, for example, by rendering the culture
broth acidic by addition of hydrochloric acid, etc.,
filtering surfactin which precipitated, dissolving the
precipitate in an organic solvent such as methanol, and
then optionally practicing ultrafiltration, treatment
with activated carbon, crystallization, etc.
Precipitation by addition of an acid may be replaced by

precipitation by addition of a calcium salt (Biochem.
Bioph. Res. Commun., 31: 488-494 (1968)).
Compounds having a lipopeptide structure derived
from prokaryotes, other than surfactin, may be used
similarly. Examples of such compounds include
plipastatin (J. Antibiot., Vol. 39, No. 6, 745-761,

Hereafter, the present invention will be described
specifically referring to surfactin as a typical
example.
Surf actin generally comprisesat least one compound
represented by the formula 1 above.
In the formula 1, of the groups having 9 to 13 carbon
atoms represented by R, the n-alkyl group is a straight
chain alkyl group, the isoalkyl group usually has the
structure ( CH3 ) 2CH- ( CH2 ) n- , and the anteisoalkyl group
usually has the structure CH3-CH2-CH ( CH3 )-( CHZ ) n- .
When surf actin is utilized, the culture broth may
be used as it is or purified before it can be used.
As will be apparent from the formula 1, surfactin
may be used as a metal salt or organic ammonium salt of
a carboxyl group derived from the amino acid structural
unit. The metal which serves as a counter ion may be
any types of metals so far as they form a salt with
surfactin, not to speak of alkali metals such as sodium,
potassium, and lithium, alkaline earth metals such as
calcium and magnesium. The organic ammonium includes
trimethylamine, triethylamine, tributylamine,
monoethanolamine, diethanolamine, triethanolamine,
--- - ----- -- ---- - ----
CA 02333601 2000-11-28
1 i
lysine, arginine, choline, etc. Among them, preferred
are alkali metal salts, particularly sodium salt.
Surfactin shows an anion activity due to the
carboxyl group of L-Glu (L-glutamic acid), L-Asp (L-
aspartic acid) therein.
The low irritation to the skin of surfactin is
considered to be attributable to the fact that surf actin
is a cyclic compound of a complexed structure and bulky
so that it has a low skin penetrability. Also, surfactin
is considered to reduce the irritation of skin-
irritating substances because of its masking effect by
surrounding the skin-irritating substances.
Further, the present invention provides an external
preparation for skin by utilizing surfactin as a
surf actant for use in external preparations for skin and
blending it together with a sequestering agent to retain
transparency.
In the present invention, the surfactant for use
in external preparations for skin used has a low skin
penetrability and is expected to exhibit the above-
described masking effect.
Further, those compounds based on surfactin but
with varied amino acid composition, for example, X in
the formula 1 is substituted by glycine, serine,
alanine, threonine, asparagine, glutamine, aspartic
acid, glutamic acid, lysine, arginine, cystein,
11

I
methionine, phenylalanine, tyrosine, tryptophan,
histidine, proline, 4-hydroxyproline, and homoserine,
the compound of the formula 2 above, may also be used.
Surfactin and the above-described compounds may
also be those obtained by other methods, for example,
chemical synthesis, as well as those derived from
prokaryotes such as Bacillus microbes, and can be used
similarly.
The sequestering agent used in the present
invention will be explained below.
If metal ions exist in transparent external
preparations for skin, they cause deterioration of the
quality of external preparations for skin, such as
generation of turbidity or precipitation. The
sequestering agent is used for the purpose of preventing
such.
The sequestering agent which can be used in the
present invention may be of any type so far as it has
an acidic group having a salt-forming ability or an
atomic group having an ability of coordination and can
sequester metal ions. Specific examples of the
sequestering agent includes L-alanine, DL-alanine,
trisodium ethylenediaminehydroxyethyltriacetate,
trisodium ethylenediaminehydroxyethyltriasetate
dihydrate, edetic acid, dipotassium edetate dihydrate,
disodium edetate, disodium calcium edetate, trisodium
12
CA 02333601 2000-11-28
edetate, tetrasodium edetate, tetrasodium edetate
dihydrate, tetrasodium edetate tetrahydrate, sodium
citrate, gluconic acid, sodium gluconate, tartaric
acid, phytic acid, sodium polyphosphate, sodium
metaphosphate, tetrasodium L-glutaminate diacetate,
etc.
These may be used singly or two or more of them may
be used simultaneously.
Of these, disodium edetate and sodium citrate are
particularly preferred.
The sequestering agent forms salts with alkaline
earth metals such as calcium and magnesium so that it
prevents the formation of salts between surfactin and
alkaline earth metals.
The external preparation for skin of the present
invention contains the above-described surfactant or
the above-described surfactant and sequestering agent.
In the external preparations for skin, the surfactant
used in the present invention serves as an emulsifier,
a dispersant, a solubilizer, a wetting agent, a
detergent, a humectant, etc. and also acts as an
irritation-reducing agent for skin-irritating
substances. There is no limitation on the form in which
the surf actant is contained in external preparations for
skin, which may be achieved by any one of dissolution,
emulsification, dispersion, mixing, etc. and may be in
13
CA 02333601 2000-11-28
I
any form such as liquid, milky lotion, gel, solid
(inclusive of powder and granules). It may be in the
state where vesicles are formed in a solution.
The amount of surfactant in external preparations
for skin is generally in a range of 0.01 to 30 wt$ . The
amount of sequestering agent is generally equivalent to
or larger than the amount of the alkaline earth metal
contained in the external preparation for skin, which
gives sufficient effects . More specifically, it may be
used in a range of 0.0001 to 3 wt%, preferably 0.001 to
0.2 wt%.
A typical example of external preparations for skin
is a cosmetic. Specific examples thereof include skin
milk, skin cream, foundation cream, massaging cream,
cleansing cream, shaving cream, cleansing foam, a beauty
wash, lotion, pack, shampoo, rinse, a hair restoration
agent, a hair tonic, a hair dye, a hair dressing,
dentifrice, a gargle, permanent waving agent, ointment,
bath additive, body soap, etc. Any type of external
preparations for skin may be included so far as it is
brought in contact with the skin when in use. Sex and
age of users are irrelevant.
The skin-irritating substances whose irritation is
reduced by the surfactant for use in external
preparations for skin according to the present invention

Production Example
Bacillus subtilis ATCC 21332 strain was inoculated
in a medium (1$ polypeptone, 0.1% RHZPO4, 0.05%
MgSO4 '7H2O, adjusted with NaOH to pH 7, balance water)
and incubated at 35'C at 160 rpm for 12 hours. 100 ml
of the culture medium was inoculated into a 2-liter
fermenter charged with a medium containing soybean
powder and maltose as main components and potassium
hydrogen phosphate, magnesium sulfate, calcium salt,
iron salt, and manganese salt as inorganic salts, and
incubated at 35r with stirring and strong aeration for
48 hours. During the incubation, caustic soda was added
to maintain the medium at pH 7.0 to 7. 5. After completion
of the incubation, the medium was centrifuged to remove
the bacteria cells and the resultant culture supernatant
was collected. A portion of the culture supernatant was
freeze-dried to obtain a dried medium preparation. The
remaining culture supernatant was adjusted with
hydrochloric acid to pH 2 to precipitate a surfactin
fraction. The supernatant was removed by centrifugation
and the surfactin fraction was dissolved in an acetone
organic solvent. The resultant solution was passed
through ultrafiltration membrane resistant to organic
solvents (Cefilt UF10,000, a ceramic membrane filter
manufactured by Nippon Gaishi) to recover a liquid
fraction, thereby removing high molecular weight
CA 02333601 2000-11-28
impurities. Then, to the liquid fraction was added
activated carbon (~ 20 m) to deodorize and decolorize
it. Thereafter, the activated carbon was removed by
filtration and the filtrate was concentrated to dryness
in an evaporator. Then, the resulting solids were
dissolved in water while adding caustic soda thereto to
maintain the pH around 7. The resultant solution was
freeze-dried to obtain purified surfactin sodium salt
powder. The dried medium preparation and surfactin
sodium salt were used in the following tests.
Surface tension tests
The dried medium preparation and purified surf actin
sodium salt were each dissolved in water in an amount
of 0.1 wt$ and their ability of decreasing surface
tension was tested. Surface tension was measured by a
plate method (25r-) using an automatic surface tension
meter CBVP-Z type manufactured by Kyowa Kaimen Kagaku
Co., Ltd. Table 1 shows the results.

Example 1: Skin irritation test of surfactant
Using a three-dimensional skin model (trade name:
Three-dimensional cultured skin model, manufactured by
Gunze), skin irritation tests were performed. As the
test substances were used the surfactin sodium salt and
dried medium preparation of the Production Example
above, and SDS (sodium dodecylsulfate), Amisoft LS-11
(manufactured by Ajinomoto, hereafter, referred to as
Amisoft). The test substances were adjusted with PBS
(Phosphate Buffer Saline, pH 7) so that they were in
various concentrations. To the thus-adjusted test
substances was exposed the skin model for 1 hour.
Thereafter, the test substances were washed and
incubated for 16 hours in a medium attached to the
above-described three-dimensional skin model. After
the incubation, a solution of MTT (3-(4,5-
dimethylthiazol-2-yl)-2,5-diphenyltetrazolium
bromide) was added and pigments were extracted with
isopropanol rendered acidic with hydrochloric acid,
followed by measurement of absorbance at a wavelength
of 570 nm. This value was called A. Also, as a control,
similar operations were repeated without addition of
test substances and absorbance at a wavelength of 570
nm was measured. This value was called B. The MTT
solution was added to PBS and extraction was performed
similarly. Absorbance of the extract measured at a
27
CA 02333601 2000-11-28
I i
wavelength of 570 nm was named C. From these values was
calculated cytotoxicity. Calculation was made
according to the following equation.
Cytotoxicity (t) = (1-(A-c)/(B-C)) x 100
Plotting the concentration of a test substance on
the axis of abscissa and cytotoxicity on the axis of
ordinate, a graph was obtained, from which the
concentration of a test compound at 50% cytotoxicity was
read. Whether this value is large or small indicates
whether skin irritation is strong or weak. Table 2 shows
concentrations at 50% cytotoxicity.
Table 2
Surfactant Concentration of surfactant
at 50% cytotoxicity
Surfactin sodium salt 24.4 %

As shown in Table 2, it is apparent that the
surfactin sodium salt and dried medium preparation of
the inventive product exhibited very low skin irritation
as compared with Amisoft and SDS, respectively.
Example 2: Skin penetration test of skin-irritating
substances

CA 02333601 2000-11-28
One (donor side) of two chambers separated by a
hairless mouse skin was filled with a phosphate buffer
(pH 7) having dissolved therein a substance having the
composition described in Table 3 and the other (receiver
side) was filled with a phosphate buffer solution (pH
7). After 5 hours, the concentration of methylparaben
on the receiver side was measured. Table 3 shows the
results. As will be apparent from the results, surfactin
suppressed the skin penetration of skin-irritating
substances.

were extracted with isopropanol rendered acidic with
hydrochloric acid, followed by measurement of
absorbance and calculation of cytotoxicity. The
cytotoxicity was calculated according to the equation
described in Example 1.
